Your stress has a daily rhythm.

Morning
Cortisol peaks after waking, priming your body for the day ahead. On low energy mornings, this window is worth checking.

Evening
By night, cortisol should drop. Test before bedtime to learn if cortisol is staying high, impeding sleep and recovery.

Day-to-day: your pattern
By testing regularly, you can see how your cortisol behaves during easy vs. hard weeks and share that data with your provider.
I am so thankful for these at home cortisol tests. They have made it so easy for me to bring real-time results to my doctor.
Mary, Verified Buyer
Easy to use tests and I exported the data and shared with my doctor as a part of my health care plan.
Lee L., Verified Buyer
I found it super helpful to be able to mesure salivary free cortisol on my own, since my doctor’s test only measures one day and I’ve wanted to see what my cortisol looks like with different activities, symptoms, and times.
